Its been a long time, it must be a movie from the 90's some time.

From what I remember the scene was someone in a secret closet that was 2 way where he/she could see out. I think they were robbing the place actually, watches and what not but im not sure.

The owner came home with a girl and he ate her out on the couch or chain and then killed her shortly after. If anyone knows the name of the movie or might have an idea please let me know, its been bugging the crap out of me!!!
